About 18 Deniston Avenue

It has a recorded floor area of 81 m² (around 872 sq ft), construction records dating it to 1930-1949 and council tax band E. The latest certificate (June 2020) shows an F (score 31), near the bottom of the EPC scale. The recommended improvements would lift it to B (score 82), a 4-band jump.
